To complicate things even further, it's the natural gas that produces fertilizer that has driven the increased food production. Coal can also make fertilizer. It's all tied together eh?
Yes it is. I don't think there is a vehicle or piece of machinery on a farm that works without the input of oil. Without it, every farmer is left standing there in the paddock unprotected with a rake and a horse that eats and f@rts alot.
Every Ozzie farmer is beholden to his Saudi masters.....and both parties know it. Cheap energy is everything, and everyone knows it. This is old ground.
There was a power outage here in our suburb last week, from 8:30am to 2:00pm. It took about 5 minutes for the whole street (we are all retired) to wander out and start bemoaning how quiet / cold / dull it is without electricity. It took less than another 1 minute to conclude that we all couldn't give a stuff about greenies or some far flung farm or mine.
All we knew was that life without power sux. We all had reserves of food for a few days at least. No biggy. None of us were equipped for even a few hours without power.
This stuff is important enough for the opposition to bring up and have a good crack at grabbing Govt. Govt knows this all too well, and doesn't muck around with the issue. People will be provided power by any means. If it means sacrificing a few far flung properties, so be it.
